Before the discovery of the \(P_{cs}(4459)\)  state, there were already a few theoretical studies on the existence of the
strange hidden-charm
pentaquarks [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]}, [9]}.
And Refs. [6]}, [5]}, [9]} proposed to search for these strange hidden-charm pentaquarks states
in \(\Xi _b(\Lambda _b)\rightarrow {}J/\psi \Lambda {}\eta (K)\) . Especially, Wang et al.found two isoscalar \(\Xi _c\bar{D}^{*}\) 
molecular states with the chiral effective field theory [2]}, the masses were predicted considering the
\(\Xi _c\bar{D}^{*}\)  molecules for \(J^P=1/2^{-}\) and \(J^P=3/2^{-}\)  as 4456.9 and 4463.0 MeV, respectively, which can
be associated to the experimental \(P_{cs}(4459)\) .
